I agree, It really depends on the size of the space and number of volunteers.
Coatesville is a steel mill town with a scrap iron yard very close to the center of town. We are a very small (8 volunteers) organization with no permanent space and we accept all bikes.
Here are few reasons that we do this: to recycle the bikes for less landfill waste, reuse any use-full parts, and lastly to make contact with our community for potential volunteers and donors.
We know of an organization in Maryland that will take the bikes we can not use and ship them overseas to other countries. Folks in these countries don't care who made it, they only care that it works.
We haven't had to ship any bikes out of the area, as many in our community, how shall I say this, are on the lower end of the economic scale. So the majority of the bikes go right back into the community.
